Joinmarket-clientserver 0.9.5:

https://github.com/joinmarket-org/joinmarket-clientserver/releases/tag/v0.9.5

Please report bugs using the issue tracker at github:

https://github.com/joinmarket-org/joinmarket-clientserver/issues

Upgrading

To upgrade:

Reminder: always back up and recreate your joinmarket.cfg file when doing the upgrade; this is to make sure you have the new default settings.

(If you are upgrading from a version pre-0.7.0 please read the "Upgrading" section in the 0.7.0 release notes.)

(If you are upgrading from a version pre-0.9.0 please read the release notes to find out how about fidelity bonds are relevant to your use-case).

First run the install.sh script as mentioned in the README. When prompted to overwrite the directory jmvenv, accept.

Note that ./install.sh -? will show the options for installation.

Notable changes

Support sending to taproot

This is mostly (though not 100%) a change to the backend bitcoin library python-bitcointx, which has been upgraded to v1.1.3 and in this version, includes the validation of bech32m as taproot addresses. (Note that the master branch of python-bitcointx now has full taproot support, i.e. constructing and spending taproot outputs, also; but we don't yet have a use case for that, anyway). Users can now send to taproot addresses via any of the user interfaces (CLI, Qt GUI, web UI).

  • b700f37 Add send-to-P2TR
  • a467ec4 upgrade to python-bitcointx 1.1.3

Extensive updates to the JSON RPC-API (jmwalletd.py); first fully working version

After a lot of testing and bugfixing, the following commits were added to patch up the JSON RPC-API feature that was added in 0.9.3. The new webUI project is using this and is now functional (alpha release coming shortly).

For those not familiar, the RPC API can be served by running the script jmwalletd.py and note that unlike other Joinmarket scripts, a wallet need not be specified, since it will allow the unlocking of any wallet (or creation of a new one) from a calling RPC client. See the user docs and API docs for details.

There are several commits, broken into two groups here:

New endpoints/functionality

  • 29b459a Add freeze method to RPC-API
  • 89896e0 Add yieldgen report endpoint to API
  • 6e07e4f Add /taker/stop endpoint to RPC
  • 28fdaa1 Allow re-unlock of wallets via /unlock
  • 3939714 Add status, label and extradata to RPC display
  • e598b35 Add RPC API endpoint for showseed

Fixes to bugs in logic, improvements

  • a0b7b38 Return TransactionFailed when insufficient funds
  • 30e96f8 Do not call stopService at exit in RPC daemon
  • 7b822a4 Do not update coinjoin state if maker cannot start
  • d493343 Ensure coinjoin state is reset if wallet switches.
  • 4389338 Make unconf unspent display default in jmwalletd
  • ed7b4e1 Fix bugs in unlock-lock logic
  • beaa8b0 fixes to API and return format
  • d4d3157 Unlock does not block waiting for sync
  • bd33b6d RPC maker/start returns 409 error if no coins
  • e6ea9d0 Update HTTP status codes returned by RPC-API
  • fe46b7e Allow RPC coinjoin taker_finished to accept unconf
  • 66d7e46 Fix RPC timelockaddress call.

Changes to dependencies

Since the introduction of the use of python-bitcointx in 0.7.0, we have effectively been using two different bindings to libsecp256k1, i.e. there was still a dependency on coincurve even though we only used it for one or two minor things. This was obviously very suboptimal, and it has now been removed. We also remove a dependency on libgmp because libsecp256k1 itself removed this dependency. Note that 68a426a was effectively overriden by the taproot update in a467ec4 but this has no functional effect.

  • 537e317 Remove coincurve dependency, use python-bitcointx

  • 68a426a Update secp256k1 to latest upstream version.

  • 5f942d5 remove all libgmp dependency references

  • c59dcd3 Remove libgmp-dev dependency

The QR code dependency is one of the more security sensitive ones, so the version was pinnned:

  • f054921 Pin python-qrcode to a specific version

Installation script improvements

You can now pass a flag to the install.sh script which makes the installation suitable for deployment with Docker:

  • c28bfd5 Add support for --docker-install with an example Dockerfile and some docs on how to use it.

Also, to aid compilation on constrained devices:

  • c0d6610 Limit number of parallel builds to CPU core count

Bugfix: Ensure displayed addresses are imported always in Qt

See #1147 and this explanatory comment for extra detail. In an unusual, but by no means unthinkable circumstance - a user deposits to multiple addresses in the Qt app, new addresses were being generated and displayed without being imported, meaning if they were paid to in the same Qt run, a rescan would be needed afterwards to pick them up. This is fixed.

  • ac8b173 Ensure all displayed addresses are imported

UI improvements

Improvement to the Qt app itself:

  • c706c6e Improve the UX of open wallet dialog.
  • f899daa Do not auto generate the QT UI code in setup.py, + 9834d73 Fix linter error

All user interfaces can make use of this extra utxo information:

  • 1cc677a Add derivation path to output of wallet_showutxos

This change (see #1111) corrects the outdated 'used' field to 'status' (since it is multivalued):

  • d110101 Rename WalletViewEntry.used to WalletViewEntry.status

Documentation

A big change is that we now have a github pages site with the Joinmarket user documentation in /docs mirrored, here, including specifically for the RPC API, here. This requires a default index.md in /docs:

  • bf6c064 Update index.md
  • bd18048 add index.md for docs site contents
  • fcd0d91 Add simple index file
  • 16cc17c address linting complaints of openapi for RPC spec file
  • 1acadb7 Self-host redoc js
  • 44ae9f2 Set theme jekyll-theme-minimal
  • 91c2c48 API documentation via ReDoc

Corrections to units and notation in the config file:

  • 1e95618 Improve examples

A clarification on the rpc_ related settings in the Joinmarket config (this is the Bitcoin Core RPC, not the RPC for Joinmarket as above):

  • b953d7e Document rpc_cookie_file and rpc_wallet_file in default config

Minor changes

Minor feature improvements:

  • f5c7f33 Allow signmessage to work with any index
  • c957c8c Read only single line with --wallet-password-stdin

Minor bugfixes:

  • ca85ac6 Don't throw when disabled socks config missing
  • cf37639 Make Qt shutdown gracefully on reactor stop.
  • 9ebd538 Removed Unicode dash.

We now only query scripts, not addresses from the RPC utxoset query; see #1124.

  • fb4644e Allow utxo address validation with script

Fixing warnings related to custom change in a coinjoin (we warn differently if you also use a different script type):

  • c5456e4 Don't show nonwallet_custom_change_warning in Qt GUI for non-cj sends
  • f741fdd Use get_txtype() / get_outtype() for address type detection

Corrects error in placement of tumbler log files, if custom data directory:

  • a1bcac9 Fix tumble log dir after load_program_config
